Description

A Weak Password Recovery Mechanism for Forgotten Password exists in Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes. A remote, unauthorized attacker may assume ownership of a user’s account by manipulating this mechanism. ArcGIS Administrators should configure an email server with ArcGIS Enterprise to facilitate user self-service password recovery. The ability for an administrator to reset a user’s password remains unchanged.
